ANSTO Minerals Report C1206 to Lagoon Creek Resources – Westmoreland Deposits<br />
SAMPLE DETAILS<br />
The samples from Westmoreland were chosen to be as representative intervals of specific<br />
recognizable lenses, which account for the majority of the resource base. Samples from both<br />
the Redtree and Junnagunna deposits have been provided. The intervals have been sampled in<br />
5 metre sub-intervals, as this was a convenient quantity for each sample bag. A brief<br />
description of the sample intervals is given in Table A1.<br />

Redtree - Garee Lens - Upper and Lower<br />
The Garee Lens occurs on the eastern side of the Redtree dyke. Mineralisation occurs as flat<br />
lying, bedding parallel zones. This lens was modelled as a single entity in 2006. Based on the<br />
results of the 2008 drilling program, this area is now modelled as having an upper and lower<br />
lens. The upper lens is associated with a characteristic coarse pebble conglomerate<br />
band. The lower lens is associated with a thicker more variable stratigraphy consisting of<br />
coarse pebbly sandstones with pebble conglomerate bands. Mineralisation is associated with<br />
hematite and chlorite alteration. Hematite is dominant in the upper Garee Lens while chlorite<br />
is dominant in the lower lens.<br />
Redtree- Jack Lens<br />
The Jack lens is a shallow, flat lying zone of mineralisation that occurs on the western side of<br />
the dyke zone. Mineralisation is associated with the equivalent horizon that hosts the upper<br />
Garee Lens. Mineralisation is typically associated with strong hematite alteration. The Jack<br />
Lens contains a higher proportion of secondary uranium minerals (autunite and torbenite) than<br />
the Garee Lens.<br />
Junnagunna<br />
Mineralisation at Junnagunna has two broad occurrence types:
